IMPROVEMENT IN SAD-IRONS.

Specification forming part of Letters Patent No. 169,496, dated November2, 1875; application tiled September 17,1875.

To all whom it may concern:

Be it known that I, OLIVER SWIFT, of Madison, in the county of Dane andState of Wisconsin, have invented a new and useful Improvement inSad-Irons, of which the following is a specification:

Figure l is a side view of my improved sadiron, part being broken awayto show the construction. Fig. 2 is a horizontal section of the same,taken through the line 0000, Fig. 1.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved sad-iron, whichshall be so constructed that the handle may be detached when the iron isbeing heated, so that the said handle will not become hot.

ward and rear parts of the upper side of which are attached, or upon itare formed, pins a.

The pins a lit into the ends of the tube B,

which is bent into proper shape for a handle,.

and has a wooden hand-piece, I), placed upon its middle part. The cavityof the tube B may be filled with plaster-of-paris to lessen itsheat-conducting power. To the inner sides of the end parts of the tube Bare attached the upper ends of two springs, G, to the lower ends ofwhich are attached two catches, D,

that pass in through slots in the said tube B, and enter notches in thepins a, to connect the handle and body of the sad-iron together. Thelower ends of the catches D and the upper ends of the pins a are beveledoff, so

that the said catches may operate automatically when the handle ispushed down upon the said pins. To the catches D are attached the endsof the springs E, the other ends of which are coiled around or otherwiseattached to a wooden ring, F, through which a finger of the hand thatholdsvthe handle may be passed, so that the catches D may be drawn outto release the pins a by drawing the ring F upward. If desired, the sidesprings C may be omitted, and the catches D held in place and operatedby the of the sad-iron is designed to be made of glass, as furnishing abetter smoothing-surface than metal.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination of the notched pins a, the tube B,provided with a wooden handpiece, I), the catches D, the springs E, andthe wooden ring F, with each other, and with the body A of a sad-iron,substantially as herein shown and described.
